Title: Determining and dilution ratios of two optically active gases - in gas mixt. using single measurement device with breakdown of signal into linearly independent components
Inventor: NESTLER VOLKER DIPL PHYS DR RE
IPC: G01J3/433
Filed: 1980-06-03
Abstract: A method of simultaneously measuring the concn. ratio and the dilution ratio of two optically active gases, which posses absorbtion spectrums overlapping in the visible, ultraviolet or infra red regions, in an optically inactive gas mixt. operates on the principle of wavelength modulation spectroscopy. Both measured variables are obtd. from the output signal of a single measurement pick-up, which is broken down into two linearly independent signal components (S1, S2). The concn. ratio Z and dilution ratio Z' are each represented as a polynomial of these signal components. The appts. is calibrated by measuring the signal components (S1, S2) of specimens having a known concn. ratio and known dilution ratio (Z, Z' respectively), these two ratios of the calibration specimens covering as uniformly as possible the entire measurement range. From the number triplets (Z, S1, S2; Z', S1, S2) obtd. from the calibration specimens the polynomial coeffts. are obtd. by multiple regression analysis using electronic circuits such that the sum of the squares of the intervals between the number triplets in the Z and Z' directions of surfaces described in three-dimensional space by the two polynomials is a minimum. These polynomial coeffts. are stored by electronic circuits in the measuring device and the concn. ratio Z and dilution ratio Z' are computed in the measurement device. Used esp. determining the ratio of CO to CO2 in a mixt. comprising these gases and N2.

Abstract: The device according to the invention comprises one or more discs which are provided on the rotor of a fluid kinetic machine for the purpose of automatic adjustment to axial thrust and which are arranged on the discharge and/or intake side of the rotor, each disc being mounted on the shaft or on the rotor neck in such a way that it can rotate and be displaced axially. In general, said mounting can also take place on an appropriate point of the casing. The discs divide the cavities lateral to the rotor into two chambers. For the purpose of automatic adjustment to the axial thrust acting on the discs on both sides, the latter are equipped with a control shoulder, each of which forms, together with the appropriately fashioned casing section, the control gap which controls the relief water flowing through the bores to a greater or lesser extent, depending on the disc position. At their external diameter, the discs are in each case equipped with a collar which covers the cylindrical surface of the rotor and with the cylindrical surface (5) in question forms a throttling gap. On the side of one chamber, the discs carry the collar which projects into a groove of the casing and forms two throttling gaps. Projecting into other chamber, the disc has, e.g. within the bores, a spacing collar.

Title: Method and system for controlling the ignition timing of an internal combustion engine
Inventor: YAMAGUCHI HIROSHI
IPC: F02P5/15
Filed: 1981-02-12
Abstract: An ignition timing control for an internal combustion engine is performed by measuring operating variables of the internal combustion engine in order to assess the operating states of the internal combustion engine and by determining an optimum ignition point as a function of the measured operating variables. The ignition point thus determined is limited in order to limit the magnitude of the ignition point variation within a certain range, as a result of which a large variation of the ignition point is prevented even if the operating states of the internal combustion engine vary from one state to another. The ignition point can be further limited in order to limit the magnitude of the ignition advance during an initial acceleration state.

Title: Sliding sphere
Inventor: NEISER CHRISTIAN
IPC: A63F9/08
Filed: 1981-09-24
Abstract: A sliding sphere, as a puzzle, has surface parts arranged on the sphere surface which are displaceable relative to one another. In order to increase the number of possible relative positions of the surface parts, and hence the attraction of the game, solid surface parts are avoided. All surface parts are displaceable on the surface of the sphere. Since all these surface parts jointly form the surface of the sphere, an integral, continuous sphere surface without projecting parts is achieved, which sits pleasantly in the hand.

Title: Stackable lid for disposable containers
Inventor: WACHSMUTH GERD
IPC: B65D43/02
Filed: 1981-11-25
Abstract: The invention relates to a stackable lid for disposable containers, in particular for meal dishes, made of aluminium foil or the like and having a profile formed in the lid surface. In order to avoid the stacked lids blocking one another and to facilitate removal from the stack, the profile is formed asymmetrically relative to the centre of the lid. The profiles consist of rib-type elevations which form individual regular geometric figures whose centre of symmetry is arranged so as to be offset relative to the centre of the lid. However, the profiles can also consist of individual elevations distributed over the lid surface or have any irregular shape. Due to the asymmetrical arrangement of the profile relative to the centre of symmetry of the lid, it is possible to stack successive lids in such a way that, by turning them through 180 DEG  relative to one another in each case, they rest on one another only on the elevations and the successive lids in the stack virtually have a spacing of the height of the profile. <IMAGE>
